Preferably, the odour treatment device 11 is located between the filter device 10 and the outlet of the second exhaust duct 8. The peculiar smell gas is firstly filtered by the filtering device 10, particles and floating dust in the peculiar smell gas are filtered by the filtering device 10, the filtered gas is subjected to peculiar smell removal by the peculiar smell treatment device 11, the particles in the peculiar smell gas are reduced to enter the peculiar smell treatment device 11, the peculiar smell removal effect of the peculiar smell treatment device 11 is improved, and the service life of the peculiar smell treatment device 11 is prolonged.
Preferably, the junction of the first exhaust duct 19 and the second exhaust duct 8 is located between the air inlet of the second exhaust duct 8 and the filtering device 10. The peculiar smell gas flowing in through the third exhaust pipeline 9, the peculiar smell gas sucked by the second exhaust device 1 and the peculiar smell gas sucked by the first exhaust device 21 and flowing in through the first exhaust pipeline 19 are collected in front of the filtering device 10 in the second exhaust pipeline 8, the collected peculiar smell gas and pollutant particles are filtered by the filtering device 10 and the peculiar smell processing device 11, the peculiar smell is removed, and then the peculiar smell gas and the pollutant particles are discharged out of a toilet, so that outdoor air pollution is avoided, and the outdoor air quality is improved.
Preferably, the first exhaust duct 19 comprises a first branch connected to the bowl 8 and a second branch connected to the second exhaust duct 8. The first branch pipes are obliquely and upwards arranged, and the second branch pipes are vertically arranged. The gas backflow prevention device 20 is provided in the first branch pipe, and the first exhaust device 21 is provided in the second branch pipe. The first branch pipe is arranged obliquely upwards, so that flushing water and excrement can be prevented from entering the first branch pipe and accumulating when the urinal 8 is flushed. The second branch pipe is vertically arranged, so that the peculiar smell gas and the pollution particles sucked into the second branch pipe by the first exhaust device 21 can be conveyed into the second exhaust pipeline 8 along the shortest distance, and the peculiar smell gas and the pollution particles are exhausted out of a toilet, and meanwhile, the vertical arrangement can also save materials and space.
The working process of the novel sanitary appliance exhaust system of the toilet of the embodiment is as follows: when no user goes to the toilet at a single side position of the toilet, the distance sensing switch 3 detects that no person exists, the first exhaust device 21, the air supply device 2 and the second exhaust device 1 are not started, and the airflow in the toilet moves according to the physical characteristics of the airflow. When a single side position of the toilet enters a user, the distance induction switch 3 detects that a person exists, the first exhaust device 21, the air supply device 2 and the second exhaust device 1 are triggered to be opened, the second exhaust device 1 positioned on the top plate of the toilet seat, the air supply device 2 positioned on the lower part of the side wall of the toilet seat are opened, and the first exhaust device 21 positioned on the lower part of the side position starts to work. Due to the fact that the nature of the polluted gas generated by excrement of a user in a toilet and the air flow organization characteristics of the toilet room are known, the polluted gas can slowly ascend from bottom to top in the toilet room. Before the peculiar smell gas and the pollutant particles generated in the urinal 18 are not diffused upwards, most of the peculiar smell gas and the pollutant particles are sucked into the first exhaust pipeline 19 by the first exhaust device 21 in the first exhaust pipeline 19 through the air inlet of the first exhaust pipeline, so that the peculiar smell gas is exhausted out of the toilet through the second exhaust pipeline 8, and the peculiar smell gas in the first exhaust pipeline 19 can be effectively prevented from flowing back to the urinal 18 by the gas backflow preventing device 20 in the second exhaust device 21. Under the action of the air supply device 2, a part of the polluted gas and the pollutant particles are sent into the third exhaust duct 9 by the supply air flow, and enter the second exhaust duct 8 from the second exhaust duct 9 to be discharged out of the toilet. The polluted gas and the pollutant particles which are not brought into the first exhaust duct 4 by the air supply flow can accelerate to rise under the action of the second exhaust device 1 right above, and enter the second exhaust duct 8 to be exhausted under the action of the flow guide cover 7 and the second exhaust device 1. The polluted gas and the pollutant particles sent into the second exhaust duct 8 pass through the filtering device 10 to filter out the particles and tiny dust in the gas, and then pass through the peculiar smell processing device 11 to remove the peculiar smell in the polluted gas generated by the personnel who go to the toilet. The polluted gas passing through the peculiar smell processing apparatus 11 is discharged into an exhaust shaft or outdoor atmosphere. When a user in the toilet leaves, the distance induction switch 3 detects that no person exists, and triggers the first air exhaust device 21, the air supply device 2 and the second air exhaust device 1 to continuously work for a period of time and then close.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to further illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which is also intended to be covered by the appended claims.
